I have an old XT with DTC 5150 (mfm) controller and a tandon 20 meg
hard disk.  I want to add another hard disk:

	How do I set the 8 switches and 3 jumpers on the controller?
	What size disk can I add?

The current cables only allow for one disk;  looks like I insert an
IDC in the middle of the wide ribbon to daisy chain it, and add a new
copy of the smaller ribbon.   I can set the motherboard switch.  I
guess I have to find jumpers on the drives to set, and terminating
resistors.

	Do I need to do anything non-intuitive with the cables?
	Is there anything I've left out?

please email any advice				- douglas ray
